Does your project need a mass flow controller with outstanding value for money? The proportional flow control valve VEMD is a closed-loop, thermal mass flow controller that supplies inert gases and oxygen with flow rates from 0 to 20 ln/min precisely and with industry-leading energy efficiency and dynamism. The valve VEMD uses piezo ceramics for flow control, which are much more dynamic and energy efficient than conventional solenoid valves.

Since the trend is moving towards smaller production batches and portable medical products, Festo developed an extremely quiet and energy-efficient mass flow controller (MFC) specifically for mobile applications such as portable oxygen system devices. The combination of small dimensions, low power consumption and low costs make it the best choice for many applications in analysis technology, automated process control and portable medical devices.
